i don't think the right answer is that you have to go to the fbi in every single case. but what ceos should recognize is there are some people in the government who can help out. the fbi has a lot of capacity and they could help mitigate the overall risk to some of these cyber intrusions. department of homeland security with the department of defense can be helpful. usually in one of the attacks the first attack you discover is not really what you should be worried about. meanwhile all of your intellectual property flows out the door for two years or secret information about transactions you may be working on is going to another country or another firm. if you see one incident it's worth it as a leader to take it sear yuzly and probably go to the fbi. >> should you assume everything in your e-mail is being read by somebody else? >> you should not assume everything is being read by the government. we of course take the fourth amendment seriously and from an operational perspective there's no reason why the fbi, the national security agency wants to read everyone's e-mail
